Google Street View has a massive update

Google announced on Thursday what the company terms the "biggest ever update" to its popular and controversial Street View map imagery Web-based service.

Google has doubled the number of Street View special collections and has updated imagery of more than 250,000 miles of roads, the company said in a blog post.

Street View coverage has been broadened in 11 countries, including the U.S., Sweden, the U.K., Italy and Singapore, and special collections have been launched for South Africa, Japan, Spain, France, Brazil, Mexico and other countries.
